Interface IAccessRule</H2>
<HR>
<DL>
<DT><PRE>public interface <B>IAccessRule</B></DL>
</PRE>
<P>
Describes an access rule to source and class files on a includepath entry.
An access rule is composed of a file pattern and a kind (accessible,
non accessible, or discouraged).
<p>
On a given includepath entry, the access rules are considered in the order given
when the entry was created. When a source matches an access
rule's pattern, the access rule's kind define whether the file is considered
accessible, non accessible, or its access is discouraged. If the source
file doesn't match any accessible rule, it is considered accessible. A source
file that is not accessible or discouraged can still be refered to but it is tagged as being not
accessible - the JavaScript validator will create a problem marker for example.
The severity of the marker created from a non accessible rule is controled through
the <A HREF="../../../../../org/eclipse/wst/jsdt/core/JavaScriptCore.html#COMPILER_PB_FORBIDDEN_REFERENCE"><CODE>JavaScriptCore.COMPILER_PB_FORBIDDEN_REFERENCE</CODE></A> compiler option.
The severity of the marker created from a discouraged rule is controled through
the <A HREF="../../../../../org/eclipse/wst/jsdt/core/JavaScriptCore.html#COMPILER_PB_DISCOURAGED_REFERENCE"><CODE>JavaScriptCore.COMPILER_PB_DISCOURAGED_REFERENCE</CODE></A> compiler option.
Note this is different from inclusion and exclusion patterns on source includepath entries,
where a source file that is excluded is not even validated.
Files patterns look like relative file paths with wildcards and are interpreted relative
to each entry's path.
File patterns are case-sensitive and they can contain '**', '*' or '?' wildcards (see
<A HREF="../../../../../org/eclipse/wst/jsdt/core/IIncludePathEntry.html#getExclusionPatterns()"><CODE>IIncludePathEntry.getExclusionPatterns()</CODE></A> for the full description
of their syntax and semantics).
Note that file patterns must not include the file extension.
<code>com/xyz/tests/MyClass</code> is a valid file pattern, whereas
<code>com/xyz/tests/MyClass.class</code> is not valid.
</p>
Provisional API: This class/interface is part of an interim API that is still under development and expected to
change significantly before reaching stability. It is being made available at this early stage to solicit feedback
from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
(repeatedly) as the API evolves.
